I can only really comment on their disco. A lot more laid back than Flex, WUK has a new mixing board and an amazing (semi-recently updated) sound system. Their Friday "Crossing All Over" club is an alternative to Flex's "London Calling" playing about the same style of music. Regular drum and bass parties and post-punk/elektro concerts are usually acceptably priced, whereas the bar is not. WUK has ingeniously rented their bar out to a private company which in turn charges astronomical prices for ridiculously small servings, for example EUR 3,10 for a 20 cL cola.
